NOTES TO THE STUDENTS

This assignment is supposed to be done in stages. The stage submissions can given to the tutor at given periods in your tutorial sessions or on an appointment basis. The tutor can see the work for certain components in the assignment to verify you are on the right track and even require you to change your solution if necessary. All work should be done to your best level so that you earn good grades.

The final submission that will be made up of All the corrected work that has been discussed with the tutor. This will be assessed and graded accordingly. This will be submitted on turn-it-in for plagiarism and marking. Your components should be labeled accordingly for you to earn marks. Part A contribute 40% to overall Assignment mark, Part B contribute 40% to overall Assignment mark 

SCENARIO: STUDENT EXCHANGE MOTSHELO (STEM)

STEM is a student entrepreneur initiative that lend student money with lower interest. Suppose that you have been approached by the STEM representatives as a Systems analyst and Designer. The representatives want you to develop a system for them to use to monitor their lending services. After a long interview with the representatives, they finally settled for the following features on the small system, that they want you to design and implement. The representatives agreed on C# programing language to be used and the system to be able to run on college computers that runs on Windows.

System Features

Feature 1. The system should allow a user to create an account for them to use it.

They will provide username, password, email, firstname, surname, physical address. These details should be saved as username#password#email#firstname#surname#physicalAddress#Phonenumber in a text file called Users.txt. Password and username can be saved separately.

Feature 2. The system should allow a user to open an account for a customer by providing the following details of the Customer: firstname, surname, customer- Number (Student number) and date. These details should be stored in a text file called customerDetails.txt with # as delimiter.

Feature 3. The system should allow users to facilitate a loan amount not more than BWP650.00 to a student with a loan account, the borrower should have loan balance of BWP00.00 and should not be flagged customer. The system should increase the loan balance by 10% every 30 days. Here the system should be able to store customer-number, loan amount and date issued in a file called loans.txt.

Feature 4. The system should allow users to list overdue loans (Customer number, Full name, contact, loan date, Number of days due), enable flagging customers as red if they have not paid a loan for more than 62 days.

Feature 5. The system should allow users to update loan balance when customer pay back the loan.

Feature 6. Every system user should login first before using the system. The system should keep a log file of every login instances in a file called log.txt. The file should contain username, login date and time.

Use the above mentioned features to attempt questions that follow. You are supposed to draw the flow charts and write the pseudocode using Microsoft word. All the answers must be clearly labeled.
